Prevent Select All In FlexGrid

I am using the 'floating text box' approach to enter data into an MSflexgrid

When a user clicks the top left cell (i.e. in the row/column headers) the whole grid is selected as you would expect.
However, if the user then types something into the activecell, this is placed in all the cells in the grid.

How can I stop entire columns and/or rows from being selected?

hmm have just noticed that none of the methods seem to get called before it selects all

Is sub-classing the only way?
I have no idea how to do that :( :confused:

No subclassing neccessary, set the AllowBigSelection property to false.

DOH!
How easy was that!:o
